A whole lot. Companies like IBM are now investing in the Unix clone Linux that they must give away to China and other countries for free instead of building up their own proprietary Unix product. A billion dollars a year, minimum, by this one company alone is going into Linux. Are you claiming they are investing that much in their version of Unix? If you are, I'd like to see some proof.
That still has nothing to do with B2K's assertion that Linux is "a way for Europeans and Asians to suck commercial Unix IP dry", which sounds like a re-iteration of the baseless claim that Linux developers are stealing IP from Unix. Notwithstanding his earlier "wait & see" stance on this issue, it appears from his statement that he has finally bought into the idea.
As you may remember, The SCO Group and its Microsoft supporters have been trumpeting this for years.
I'd just like to know if anyone has yet found any actual proof of it.
